Death Mesh & Root Cages. What Are They and How Do They Affect My Plants?

Have you ever had a plant mysteriously die? You followed all of the recommendations for watering, sunlight, and temperature. You did everything right.

So what caused it?

If you’re a beginner, you’re in luck. You’re unlocking the information that even some seasoned houseplant enthusiasts don’t know about.

Let’s say you bought your plant from a retailer. Whether it’s a corporation or a local nursery, chances are that silent killers are lurking in its soil.

The common practice for smaller plants--seldom used for the larger ones--is to wrap the root system in a mesh-like material, also known as root mesh. They may also use plastic pots with vertical slots in them called root cages.

First, let's cover root mesh. The mesh is often used to keep the live merchandise from dying in transport or on a shelf waiting to be purchased.

Short term, it can be beneficial. It helps regulate moisture while growing as most companies use hydroponics for their product. It also helps the plant produce more foliage, preventing it from filling the pot or planter. This makes them look as lively as possible while they live in less-than-ideal conditions.

Long term, the mesh is essentially a death trap for your plant. The material will ‘strangle’ the root system as it continues to grow.

The best way to ensure your plant has the best opportunity to grow and thrive is to remove the mesh. But, be careful. A plant’s root system is fragile, and we don’t want to break or remove any of its roots. If you break some, it’s not the end of the world—or your plant.

First, carefully remove your plant from the pot, and break up the soil. If there is no death mesh present, great! If there is, don’t worry, we can get it off. Simply find the upper section of the mesh near the soil surface. Grabbing the bottom of the mesh could be tricky, especially if the root system is large. Start to tear the mesh downward. Sometimes roots will have started to puncture the mesh, so you’ll want to pick another spot at the top to start again. Patience is key. Go slowly to make sure the mesh isn’t catching on any roots.

Now that we've covered root mesh, let's talk root cages. These plastic cups, like the root mesh, restrict plant growth.

From my perspective, removing these cups is more challenging compared to the mesh due to the tougher material they are made of. The material is more durable, making it difficult to tear or break.

To remove these, try and wiggle it off as best you can. I usually try to compact the roots and soil by sticking a rubber eraser into the slits of the cup. You don't have to do this, but I believe it's easier to avoid damaging protruding roots. Remember: If you do damage or break some roots, it's okay. Just try your best.

Let’s recap: Death mesh and root cages are used to limit plant growth. Their use can ultimately lead to plant death, but this can be remedied by simply removing them.

So when you buy a new plant, try to make it a habit to check the root ball when you get home.
